Hobart dishwasher leaves white film or spots on glasses and dishes.

Safety first: Allow wares to cool before handling.

• Check water hardness: Test incoming water hardness. If above Hobart’s recommended range, install or service a water softener.
• Adjust chemicals: Increase detergent and rinse aid dosing within supplier guidelines to improve soil removal and sheeting.
• Verify rinse temperature: Ensure final rinse temperature is at specification to aid drying and reduce spotting.
• Descale machine: Run a descaling cycle using a Hobart-approved descaler to remove internal limescale from the tank, booster, and arms.
• Monitor results: If spotting persists, work with your chemical supplier to fine-tune the chemical program.
